|Abstract:||A new three-component inorganic ion exchanger, zirconium(IV) sulphosalicylophosphate(ZSP) has been synthesized under varying conditions. Sample ZSP<sub>5</sub> was chosen for detailed ion exchange studies owing to its highest ion exchange capacity, good appearance and chemical stability. ZSP<sub>5</sub> has been characterized on the basis of chemical analysis, pH titration, FTIR, TGA and X-ray analysis. The distribution coefficients (<i style="">K</i><sub>d</sub>) of 16 metal ions were determined in different pH systems, demineralized water and 0.1 M NH<sub>4</sub>NO<sub>3 </sub>solution. On the basis of difference in distribution coefficients (<i style="">K</i><sub>d</sub>) some analytically important separations of metal ions have been achieved. A highly significant factor, <i style="">K</i><sub>d</sub>Al<sup>3+</sup>/<i style="">K</i><sub>d</sub>Mg<sup>2+</sup> has been utilized for the separation in their, synthetic mixtures and antacid formulations.|
